I have done some searches on this topic and it seems that I may be out of luck since it could be any random issue/change in my project… but here goes nothing:
I had no issues packaging and launching the default Dev build to my android device…
I changed it to the Production build to see if it would speed up rebuilds…(maybe a bad assumption on my part, assumed it may leave out some debugging files)
Production build was also working fine and launching on my device…
After a day or so of modifying my BP and C++ code… suddenly I keep getting the same error when trying to launch on my device. I have tried changing many of the build params etc… restarting my editor, VS, computer…
Play in editor works flawlessly still, but the package fails every time I try to install it on my phone now, whether in Dev or Production build…(though I havent tried debug).
This is a snip of the relevant error:

PackagingResults:Error: Error Launch failed! Unknown Error
Interestingly, it is looking for Debug apk, regardless of me selecting between production and development, (and I have never once selected Debug build anyway)… Though maybe this is just the typical Android notation of a build either being Debug or Release…
I have tried selecting the full rebuild option in packaging settings, cleaning/rebuilding in Visual studio… everything works fine for PIE… no errors pop up.
Is there any file I can delete from my project maybe to force the tools to start over?
